解説
エチレンとプロピレンの共重合体からなるゴム(EPR)，およびEPRに第三成分として少量のエチリデンノルボルネンなどのジエン類を共重合させたゴム(EPDM)の総称．耐オゾン性・耐候性に優れている．
説明
Ethylene-propylene rubber (EPR, or EPDM,) is a copolymer of ethylene and propylene. It has much of the chemical resistance of the related plastics: excellent resistance to heat and oxidation; good resistance to steam and hot water. It is used as a standard lining material for steam hoses; widely used in chemical services as well, having a broad spectrum of resistance.
定義
An elastomer made by the stereospecific copolymerization of ethylene and propylene. Has no unsaturation; cannot be vulcanized with sulfur but can be cured with peroxides.
